New in Version 2.5

I have a recording with some unusable data in it, is there a way to trim out the useful parts?


New to Version 2.5 is the "Trim Recording" tool represented by this toolbar icon:

To use this tool:

  1. Begin by clicking on the Trim Recording Icon
  2. The Playback Bar will change its display. Now you will see a pair of red triangles below the bar
  3. You can click, hold and drag the sliders to the desired locations. You can trim the beginning or end or even a section out of the middle.
  4. When you have defined the section of the recording you want to snip and save, click the Trim Recording icon that is to the right of the Playback Bar
  5. The "Trim Recording" dialog box will appear
    1. You can give the new recording a different name
    2. You can open the recording after trimming
    3. You can choose to delete the original recording. By default, the original recording will be kept and a new recording will be created identified by "trim" in the name.
    4. Make your selections and click "OK" to complete the task

Can I amplify multiple recordings at the same time?

Yes you can.

Starting in Version 2.5, in Motion Explorer, you can select multiple recordings to amplify all at once.

On your tree-view list inside a collection, you will see the videos listed. Any video with a green check has been amplified. Any video with a yellow caution symbol needs to be amplified.

From within a collection, use the "SHIFT+Click" or "CTRL+Click" to select multiple recordings. After the necessary recordings are selected, click on the "Amplify Recording" icon from the ribbon bar. Note - the icon will also only appear active when a recording which needs to be amplified is selected.

The attached recording gives a short demonstration of this behavior.

Can I see the phase difference between two ROIs in a recording?


New in Version 2.5 is the ability to compare waveform peaks and find a relative phase difference between the waveforms.

To compare phase readings follow these steps:

1) Place two ROIs in the recording and let the software perform its calculations

2) (Optional) You can use the Spectrum to identify the peak frequency. If you know the frequency, this is not necessary.

3) Open the Time Waveform displays

4) Right-click in the plot that you would like to use as the Master for the reference

5) From the new pop-up menu, select "Set Phase Reference"

6) Enter the frequency at which you want to do the comparison

7) You will see the frequency appear at the bottom of the Master waveform

8) The other waveform displays will have a relative phase between their waveform and the master's

The video below gives a short demonstration comparing the relative phase between two ROIs in the X-axis

How can I reduce the size of an MP4 export? (Video Format and Quality)

Version 2.5 UPDATE

Use the "Export Specification" tool to change the quality and content of your MP4 exports.

New in Version 2.5 is a tool that you can use to determine the quality of the MP4 created during export. You have three choices: Low, Medium and High. High will produce the highest quality video and the largest file size. Low will result in the smallest file size and the lowest quality video. This selection determines the level of compression that is used when producing the video.

This tool also lets you determine the Video Format for the MP4. Available choices are:

Full HD (High Definition) 1920x1080

HD (High Definition) 1280x720

SD (Standard Definition) 640x480

The larger the format, the larger the size of the produced file.

The table below gives approximate file sizes for a 1 second video in each format at each quality.

High277 KB144 KB30 KB
Medium277 KB144 KB30 KB
Low215 KB141 KB30 KB

The Export Specification tool looks like this (with the Video Format and Quality lines in the green box) and will appear after clicking on the "Export Video" icon  found to the right of the Playback Bar.

Can a recording taken in a previous version of software be used to make a Shaft Measurement?


If you have an old recording which has a good view of a shaft, you can open it in Version 2.5 or newer of Motion Explorer and add one of the Shaft Measurement ROI boxes (Horizontal Shaft or Vertical Shaft) to the shaft location. Keep in mind, the shaft must be large enough, have good lighting, and be either horizontal or vertical. If you only have a small portion of shaft in the background, it may not provide good measurements.

Can I make a measurement on a shaft or rotating component?

Version 2.5 is the first version of RDI Technologies™ software where rotating shafts can be measured. However, you must use one of the specific Shaft Measurement ROI's, Horizontal Shaft or Vertical Shaft. A standard XY ROI cannot make this measurement.
